-------------------------------------
Summary: Improve validate-source-patterns in build.xml (e.g.,
detect invalid license headers!!)
Key: LUCENE-6732
URL: https://issues.apache.org/jira/browse/LUCENE-6732
Project: Lucene - Core
Issue Type: Improvement
Reporter: Uwe Schindler
Assignee: Uwe Schindler
Today I enabled warnings analysis on Policeman Jenkins. This scans the build
log for warnings by javac and reports them in statistics, together with source
file dumps.
When doing that I found out that someone added again a lot of "invalid" license
headers using {{/**}} instead a simple comment. This causes javadocs warnings
under some circumstances, because {{/**}} is start of javadocs and not a
license comment.
I then tried to fix the validate-source-patterns to detect this, but due to a
bug in ANT, the {{<containsregexp/>}} filter is applied per line (although it
has multiline matching capabilities!!!).
So I rewrote our checker to run with groovy. This also has some good parts:
- it tells you wwhat was broken, otherwise you just know there is an error, but
not whats wrong (tab, nocommit,...)
- its much faster (multiple {{<containsregexp/>}} read file over and over, this
one reads file one time into a string and then applies all regular expressions).
